PORT ST. LUCIE, Fla. — Major League Baseball’s investigation into Jenrry Mejia’s age and identity has concluded and both were confirmed as accurate, the Mets announced yesterday.

Mejia was unable to pick up his visa in his native Dominican Republic because of the U.S. consulate’s decision to investigate him. The Mets insisted the procedure was random. Someone outside the organization with knowledge of the situation also believed it to be random. That person spoke on condition of anonymity because they are not authorized to speak on team matters.

Mejia is expected to report to Mets camp in the next couple days; he had been working out at the team’s academy in the Dominican Republic in the meantime. The 23-year-old pitcher will work as a starter this spring.

Mejia appeared in five games last season for the Mets. Three were starts. He posted a 5.63 ERA in 16 innings and accumulated nine walks to eight strikeouts.

• Manager Terry Collins announced Kirk Nieuwenhuis will get the first crack at leading off for the Mets this spring, Saturday against the Nationals in the teams’ Grapefruit League opener.

"Obviously, it’s a compliment," the center fielder said.

"I’m hopeful to take that spot and run with it. You kind of set the tone for the game and it’s a big responsibility. You just got to be aggressive and smart — that’s the biggest thing."
